The DR ORT 135.7 was an overhead line inspection car of the Deutsche Reichsbahn , five of which were built by Waggonbau Görlitz between 1956 and 1958 .
history
When the Deutsche Reichsbahn rebuilt and expanded its electrical route network in the GDR, it needed a vehicle to maintain and service the overhead contact line systems . In 1956, a total of 3 railcars were built in Waggonbau Görlitz and another 2 railcars in 1959 . Until 1958 the first vehicles were designated as Magdeburg 700 001, Magdeburg 700 002 and Hall 701 427, then they were renamed ORT 135 701 to 703. The vehicles delivered in 1959 were immediately given the names ORT 135 705 and 706. The missing number ORT 135 704 was occupied by a Dutch pre-war tower car, which until then had been run under Hall 157 859. In 1970, the DR converted the vehicles to a computerized numbering scheme and from then on referred to them as 188 001–003 and 188 005–006. The last redrawing fell on January 1, 1992 and produced the numbers 708 001–003 and 708 006, 188 005 was no longer redrawn because it retired from service on March 1, 1990.
Whereabouts
708 002 and 003 were scrapped in the Leipzig South depot in 1998. 708 001 came to the Staßfurt Railway Friends. 188 005 has been preserved in a desolate condition on the Niederlausitzer Museumseisenbahn . 708 006 received a new general inspection in 1999 and belongs to the DB Museum Halle (Saale) .
Structure and equipment
The 13.1 m long 188.0 is entered via two sliding doors in the middle of the vehicle , here you get directly into the 6.8 m long workshop room, which also houses the observation dome and the toilet, past the dome you enter through a revolving door the driver's cab 1 and past the toilet again through a door into the 2.7 m long lounge with cupboards, a table and chairs; the second driver's cab is separated from this room. The observation dome, which also serves as an exit, the aerial work platform and the RBS 58 measuring pantograph are located on the roof . In addition to checking the zigzag run and measuring the height of the contact wire, this bracket is also used for earthing, without which an exit is not possible and also life-threatening. The aerial work platform, located between the bracket and the dome, can be raised by 1,600 mm and swiveled mechanically by 90 degrees on both sides; it measures 3,740 mm by 1,970 mm.
Drive and brakes
The 188.0 is guided in the track by a 2-axle leaf-sprung running gear with a 7.0 m wheelbase, the axle below the dome is the drive axle and the one below the lounge is designed as a running axle. To brake the railcars by a Knorr - Compressed air brake Kp, which brakes both axes 8 brake pads, in addition, a spindle brake is provided in each guide space, acting on the respective next wheelset.
Drive and electrics
The 188 001 and 002 were supplied with a 6-cylinder - diesel engine of the type EM 6-20-7, this provides at 1,800 min -1 a power of 74 kW (100 hp). In the other three railcars, the factory used engine 6 KVD 14.5 / 12 SRW, which at 1,800 min −1 99 kW (134.6 hp), in 1977 all vehicles were converted to the technically more stable engine 6 KVD 14 , 5 / 12-1 SRW, of a power increase to 103 kW (140 hp) at 2000 min -1 effected and made the cars more reliable. The torque is transmitted from the engine to the drive gear set via a single-disc dry clutch and a 4-speed change gear . The on-board network works with 24 V and is fed by a generator on the drive motor and by a separate on-board power unit - below the dome platform. One serves as a safety device Aufforderungssifa 66 , an inductive magnet but does not exist.
